A shingle blow-off is a roofing concern you don’t want to experience. Not only is it a hassle to repair or replace, it’s a clear sign that there’s something wrong with your roof – either it’s old or has suffered from some hidden damage.
ReNew Home Designs, your expert local roofers, shares the three likely causes of shingle blow-offs.
1. Old Age
The most likely cause of shingle blow-offs is age. Specifically, when your roof has exceeded its maximum operating life span. Although durable roofing materials like asphalt can last between 10 to 20 years, this depends on the kind of care it’s given.
Blown off shingles are one tell-tale sign that your roof is near the end of its expected service life. It is also a prelude to more serious roofing concerns, such as a leak. We recommend you have us do roof replacement as soon as possible so you can avoid having your roof experience more debilitating problems.
2. Improper Installation
Shingle blow-offs that occur on a fairly new roof may be due to improper installation, and the likely culprit is nails used to fasten them in place. More often than not, a blow-off occurs when the nails are too high up on the shingle instead of properly fastened across the nailing strip. Fortunately, this is slightly easier to repair as it only requires roof repair to address the certain portion of the affected roof.
3. Hidden Roof Damage
Finally, a shingle blow-off may occur due to hidden and existing roof damage. In most cases, this occurs when the plywood sheathing or OSB board under the shingles is suffering from long-term moisture damage due to leaks. When these components fail, the nails holding the shingles in place come loose and they can get easily blown off by the wind.
Underlying damage is trickier to address since you need to have a roofer do an inspection for you to know if what you need to do is repair work or a full replacement. Fortunately, we offer just that as part of our exterior home services.
